Amazon India — refusing to give home delivery

Address:

637201

Sir/madam, i am from sankagiri, salem, tamilnadu. I purchase products from amazon often, on 18 nov 2017 i had ordered for a http://amzn.in/81yru7G, glamio military solid cotton cargo pant. I gave my home address, our pincode is 637301. When we enter this pincode, we have delivery range but the courier company in our town is refusing to do homedelivery saying its out of range. But i have all the proof that my home is in the range. They are not doing their duty properly. They are asking us to come and collect the parcel. This is not the first time. Kindly do the need. Since because your site says our address is eligible, we are ordering, or else why are we going to order? Kindly ask them to do their duty.
I[censored] need any proof that my house is in the range, i am ready to provide. We asked the delivery person’s name she s refusing to give her name. Kindly do the needful
